‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

bit 31-0

CSSL<31:0>: ADC Input Pin Scan Selection bits

1 = Select ANx for input scan; CSSLx = ANx, where ‘x’ = 0-31

0 = Skip ANx for input scan; CSSLx = ANx, where ‘x’ = 0-31

Note 1:

2:

For devices with 64 pins, CSSL28 selects IVREF (Band Gap) for scan; CSSL29 selects CTMU temperature

diode for scan; and CSSL30 selects CTMU input for scan

On devices with less than 32 analog inputs, all CSSLx bits can be selected; however, inputs selected for

scan without a corresponding input on the device will convert to VREFL.

1 = Select ANx for input scan; CSSLx = ANx, where ‘x’ = 32-50

0 = Skip ANx for input scan; CSSLx = ANx, where ‘x’ = 32-50

Note 1: For devices with 100 or more pins, CSSL48 selects IVREF (Band Gap) for scan; CSSL49 selects CTMU

temperature diode for scan; and CSSL50 selects CTMU input for scan

Note: The ANx inputs in this register only support devices with 100 or more pins.
